Patented Oct. 8, 1929 PATENT OFFICE CHARLES J'. MCCLINCH, OF BRIDGEIPORT, CONNECTICUT WINDOW-SCREEN FASTENER Application filed September 13, 1926. Serial No. 135,033.

My invention refers to improvements in means for detachably securing window screens to window frames, whereby a screen can be quickly secured in position in a window frame in such a manner that the screen will be adapted to swing out from the bottom and removed if desired with little or no trouble. The device is more especially adapted for use on full length screens, though it may also be used to advantage on half length screens. The invention as used upon a full length screen, is such as to permit both the upper and lower window sash to be raised or lowered without interfering with the screen or adjusting the same in any way.

The object of my invention is to provide means for the attachment of a window screen which will not-mar the appearance of the window frame or screen, will not be visible from the outside of the latter and thus less liable to be tampered with. Also to provide a novel form of hanger which may be inexpensively made and sold at a popular price.

With these and other objects in view, the

invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claim may be resorted to without departure from the spirit, or sacrificing any of the advantages of the invention.

Similar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawing forming a part of this specification and upon which Fig. 1 shows a perspective view of a window frame and sash together with a full length window screen hung in the upper part of the frame by means of my improvement.

Fig. 2 shows an enlarged cross-sectional view taken through the upper part of the window frame, sash and screen on line AA of Fig. 1, the screen being in a position for attachment to the frame.

Fig. 3 is a further vertical sectional View taken on the same line but with the screen attached and in a closed position.

Fig. 4 shows a detached perspective view of one of the two angular shaped plates for attachment to a window frame forming the fixed members of the hanger, and

Fig. 5 is a somewhat similar perspective View of one of the two co-acting plates for attachment to the upper end portion of the screen for slidable engagement with the plates secured to the frame.

The screens for which my hangers are best adapted, are those which are made to fit into a window frame and particularly against the inner edge portion of the outer window casing with the inner-face of the screen positioned against the outer-face of the outer window stop. This obviously positions the screen in spaced relation to the uppersash which is free to slide between said outer stop and the intermediate parting strip.

The window frame and its sash as shown on the accompanying drawing, is illustrative of a common form of window construction, and

wherein 6 represents the outer side members of a window frame, 7 the sill and 8 the top member of the casing. 9 indicates the body of the frame, 10 the parting strips and 11 the outer stops. The upper sash 12 is positioned between the parting strips 10 and stop 11, and is adapted to he slid vertically with relation thereto.

My improved hanger ispreferably formed of sheet metal which can be stamped andformed up by automatic machinery, and is made up in pairs, two pairs being required for each screen. Said pairs being substantially alike, except that one is a right and the other a left, necessary for attachment to the opposite edge portions of the window casing.

ne pair of said hangers being designed for slidably connecting the upper corner portions of the screen to the inner corner portions of the window frame. The hanger member 13 shown in Figs. 2, 3 and 4, is of a general triangular shape and is provided with an inwardly disposed flange 14, along its upper edge portion and a somewhat similarly formed inwardly disposed flange 15 projected from its under inclined edge. The said inclined flange forming an inclined guide against which the incline of the co-acting hanger member 16 slidably engages.

This hanger member 13, is provided with a screw hole 17 in its upper flange 14 for attachment to the stop 11, by means of screws 18, and further contains a hole 19 in its body portion to receive a screw 20 for the further attachment of the member 13 to the side stop 11.

Vhen so attached, (see Fig. 2) the inwardly disposed flange 15 is arranged at an incline corresponding of course, to that of the member 13 attached to the opposite strip 11 in the other side of the window frame.

These two hanger members thus similarly attached and positioned in opposite relation, in the upper corner portions of the frame, are adapted to be simultaneously engaged by the co-acting members 16, secured to the upper corner portion of the screen.

These screen members 16, are each provided with a flange 21 having holes 22 to receive screws 23 for attachment to the screen frame. This hanger member 16, like the co-acting member 13, is provided with an inclined outwardly disposed flange 24-, which extends inwardly fromthe inner-face of the screen in position for ready engagement with the incline flange of the co-acting flxed member 13.

It will thus be seen that with the two parts of the hanger attached one to the window frame and the other to the window screen, the two inclined flange portions may readily be brought into engagement, positioned, and held as shown in Figs. 2 and 3, and when the screen is finally adjusted and positioned within the frame, the lower portion may be readily fastened to the frame by means of a hook 25 and eye 26, one secured to the screen and the other to the window frame.

Having thus described my invention, what- I claim and desire to secure by Letters Patent is A screen hanger formed of two triangular shaped sheet metal members, one having two of its edges disposed to one side forming flanges, and the other having one of its edges disposed to one side and another disposed to the opposite side, one flange of each of said members being provided with means for their attachment, and the other flange of each member adapted to engage and co-operate in the support of a screen on a window frame.

Signed at Bridgeport, in the county of Fairfleld and State of Connecticut, this 10th day of September, A. D. 1926.
